Abstract
This invention relates to a high-strength, austenitic, stainless steel, and to a method of its production. A method of producing a high-strength, austenitic, stainless steel characterised by air-melting a feedstock of super austenitic stainless steel, introducing nitrogen at 1520° C. to 1540° C. by way of electrolytic manganese containing 6 wt % nitrogen, then low carbon ferro-chrome, adding boron when the other two alloys have been fully absorbed into the molten bath, allowing the bath to cool, casting the metal at 1480° C. to 1495° C., and subsequently subjecting the castings or metal to a solution heat-treatment at 1400° C. to 1160° C. A further aspect of the invention is a high-strength, austenitic stainless steel characterised by the following chemical composition by wt %:</PTEXT>A still further aspect of the invention is a weld rod or wire or a weld metal of the composition above definded.</PTEXT>
